ROTARY ENG'IN E.

SPECIFICATION forming part of Letters Patent No. 484,769, dated October25, 1892.

Application filed July 29, 1891.

To all whom t may concern-.-

Be it known that I, FRANK. M. BAILEY, a citizen of the United States ofAmerica, residing at Lima, in the county of Livingston and State of NewYork, have invented certain new and useful Improvements in RotaryEngines, ofwhich the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to a new and improved rotary engine, and has forits object the production of an improved engine of this class whichshall be positive in its action and composed of but a minimum number ofparts.

The invention comprises the detail construction, coinbination, andarrangement of parts, substantially as hereinafter fully set forth, andparticularly pointed out in the claim.

In the accompanying drawings, Figure 1 is an end elevation with thecylinder-head removed. Fig. 2 is an approximately-horizontal sectionalview on the line ac, Fig. 1. Fig. 3 is a view in side elevation, partsbeingiu dotted lines.

Referring to the drawings, A designates a cylinder or circular chambersuitably mounted in position; a, the steam-inlet port opening into saidcylinder at the upper portion of one side thereof, and a thesteam-outlet port opening into said cylinder at about the center of itsopposite side. In the inner surface of cylinder A is a groove or recessa, which eX- tends from the outlet-port a to the top of said cylinder,the same serving as. a backpressure relief. The head-plates a2 arerigidly secured in place by threaded bolts c3, and to each of thesehead-plates are secured stuffingboxes b, through which the main shaft Bis passed.

C is the piston head or wheel rigidly secured upon or-formed with shaftB and located Within cylinder A. In this head O are two oppositelongitudinal slots or openings d, which extend from end to end of thehead and from shaft B to the outer periphery of said head. IVithin theseslots or openings are wings or plates D D', which fit snug in saidslots, the outer ends of said wings being slightly curved or beveled toconform with the inner surface of cylinder A, with which they Serial No.401,028. (No model.)

openings d, which recesses are above the pro- 6o truding ends of thewings when the latter pass the steam-inlet port. In the end faces ofpistoii-head C are circular grooves or recesses e2, adjacent to shaft B.Into these grooves or recesses c2 project cams e3, formed 65 on theinner faces of the cylinder-heads. The eXtreme outer or thickenedportions of these cams correspond with the steam-inletV port.- that is,they 'are arranged on aline with said port, so that as the plates orwings are passing the inletport they are held out tight against thecylinder and all wabblin g or shaking is prevented. Thus the cams act aslocks for the Wings or plates and render the action of the latter sureand positive.

The operation of my improved engine 1s as follows: The rotary shaft isturned by ahandwheel, as E, until one of the wings is brought justbeneath the steam-inlet port, when the admitted steam bearing thereonwill impart 8o motion to the piston-head, and the steam being confinedto the space formed between the wing and the point of contact at the topof the cylinder the piston-head will be driven around, and upon the wingpassing the escapeport the steam will pass thereout. By this time theother wing has passed over the steaminlet port and a fresh impetus orcontinuous power is had by the steain-pressure thereon, said wings beingheld tight against the cylinder as they pass said steam-inlet port bythe extreme outer portions of the lockingcams of the cylinder-heads.

From what has been said it will be seen that I have produced a rotaryengine which IOO hence there is noljerkingorffunevnnessfof movement andthe wings are held rmly in" In connection with myimproved rotary engineI preferably employ au v'automatic gov ernor, which latter forms thelsubject-matter of a separate application for patent, filed August 22,1891, Serial No. 463,443. Briefiydescr1bed,'said governor comprises twoweighted arms pivotally mounted in the' pulley, from which the motion ofthe engine is secured, said arms being forced outward by centrifugalaction and thereby through `theagency ofan arm controlling the positionof the valve in the steam-inlet pipe. f Ijfis a -pulley ymounted `onshai'tB; ff, tivo weighted arms pivoted" at'fl'between lugs of saidpulley; f 2, cross-bars proj ctihg from said arms, and f3"'coil"springsconnectedratl their ends to said cross-bars. ff To theinne periphery ofpulley 'F are conneetediat springs `g, theouterifree'ends of which *bearupon arms fat the pointswherethe latter project through openingsdn saidpulley. l G isasliding sleeve oncl'lar 'on-"shaft/B, and` the 'sameisprovided with" a`circ`un1fr entlal vgroove or recess g', whereinproject the rounded ends of arms f; To an Hencircling band g2 of thissleeve or collar is rigidly connectedfone endof aniarm g3, the outerend'of which is pivotally connected-to an arm h,the hub of which iskeyed' orloc'ked "upon the shaft h' of a valvelocatedin the steam-inletpipe.

A milled nut his on the threaded portion of this screw h3, andby means thereof theproper tensioncan "be,placed'` uponfthfe gdvernor,according as it is desired to increase or diminish the speed thereof. Inthis Way the speed of the engine is automatically controlled by thespeed set 'for the band-wheel or pulley, the speed of the lattercontrolling that of the former.
